- Human sFRP-4 Antibody
- Antibody type
- Polyclonal
- Description
- Immunogen affinity purified. Detects human sFRP-4 in direct ELISAs and Western blots. In direct ELISAs, approximately 50% cross-reactivity with recombinant mouse (rm) sFRP-4 is observed, and less than 5% cross-reactivity with recombinant human (rh) sFRP-3, rhsFRP-1, and rmsFRP-2 is observed.

- Experimental details
- Detection of Human sFRP-4 by Western Blot. Western blot shows lysates of OVCAR-3 human ovarian carcinoma cell line, human ovarian cancer tissue, and MCF-7 human breast cancer cell line. PVDF membrane was probed with 2 µg/mL of Goat Anti-Human sFRP-4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1827) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for sFRP-4 at approximately 53-55 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.
